Opinions on Graaf Amps

Does anybody have any expereince with Graaf OTL amps? I'm especially interested in the little GM 20 but don't have a chance to listen to it where I live. Has anybody heard it? In my search for a new amp I have listened to the Carys (572s) and found them overall too bloomy. I don't like tube amps that try to sound like solid state (i.e., Audio Research or BAT) but I also don't want the tubes to color the sound too much. I've tried the Atma-Sphere S 30 which sounded terrific in my system, open, airy and very musical, but it just runs too hot. So now I am considering the Graaf or perhaps an Air Tight. Any thoughts would be appreciated.

My system:

Joule Electra LA 100 MK-III
Merlin VSM + BAM
Audiomeca Keops as transport and Audio Logic 2400 DAC
JPS Super + speaker cables, FX interconnects, and Power Cords

Many thanks,

Dr V

I purchased a pair of Sonus Faber Guarneri's and have tested maybe 10 amps. I have kept the Graaf GM20 otl as my final choice. It is quiet, accurate, detailed warm.
I am listening to the system at low volumes in a 10x11 office so the mono route is not neccessary (but at louder volumes I find the bass control lags). This is an exceptional rare product that continues to fascinate me with musical enjoyment. I have ordered a GM200 for another system and will be recieving it soon, GRAAF makes products of high quality and refinement. Such products are becoming harder and harder to find in todays cluttered marketplace. I am glad I stumbled on this beauty.
